Altar of the Wretched // Wretched Bonemass

Description

Altar of the Wretched // Wretched Bonemass is a double-faced artifact card from The Lost Caverns of Ixalan Commander that crafts into a creature using exiled cards. The front lets you sacrifice a nontoken creature on entry to draw and mill cards equal to that creature's power and has a craft activation plus a graveyard-return ability. The back, Wretched Bonemass, becomes a Skeleton Horror whose power and toughness equal the total power of the exiled cards used to craft it and gains multiple keywords if any exiled material has them.
